Does anyone know *exactly* what plug this is, because there are many similar ones? Will be powering it from a 12V DC-DC converter not the supplied AC wall-wart, so need to make up a cable...
 
Sometimes called Coaxial Connectors, Plugs or Jacks, Ive always known them as DC Barrel Connectors for Laptops, trick is to find out what size they are (Alphabet Band) and to what type of International Standard as there are lots of them, they may fit and work but if not correct they will not perform correctly under a DC Current Load.

I know it's a barrel connector, I was hoping somebody could tell me exactly which one because there are *lots*, all slightly different.

The most common ones are 5.5mm external diameter and either 2.1mm or 2.5mm internal diameter, but there are many others used by awkward manufacturers who seem determined to stop you using anything other than their supplied AC adapter -- which is not helpful when you need to the router to carry on working when the boat inverter is off... :-(

I know the supplied AC adaptor is 12V 2A, the 12V DC-DC converter I'll be using (Victron) is rated at 12V 5A so no problem.

Why not just break the cable and connect directly to your 12v power supply source using the connector you have. Should you wish to return to using the wall plug just join the cable with a suitable inline connector of your choice at the point you cut it.

That's the alternative, but I'd rather keep the AC adapter intact if possible (the router will probably be on a Three contract) -- a barrel connector is dirt cheap, it's just a question of finding the right one...
